When the girl’s mother, Zoe Stewart, realised that the floppy-eared Mr Rabbit – which had been with her three-year-old daughter Ruby almost since birth – was lost, she quickly turned to her social media followers on Twitter, Facebook and Instagram for help.

The 29-year-old mum posted a frantic request on Twitter for those with information to come forward and the retweets received from thousands (including Mother&Baby’s columnist Cherry Healy) has been extraordinary and launched a nationwide rabbit hunt.

LOST!!!!! Lovely people of London please keep your eyes open & retweet if you can, one super upset wee girl :( pic.twitter.com/Vb3Ufcf1F3

Unfortunately, Mr Rabbit’s location is still unknown but Zoe and her husband Keith have been touched by the response. Speaking to the MailOnline, Zoe said, 'The response has been unbelievable – I didn't know there were that many nice people out there. I've had 50 people offering to send me their toy rabbits, and even people from America offering to send Ruby a postcard from Disneyland so she thinks Mr Rabbit is having a nice time on holiday.'

The original Mr Rabbit is described as ‘a little tatty’, smelling ‘of Olbas Oil’ and having no stuffing in his neck ‘from being hugged so much so he flops to one side.’
